ICOPPER-SMELTING FURNACE-f SPECIFICATION forming part of Letters PatentNo. 746,25,'dated December 8, 1903. Application filed August 26, 1903.Serial No- 170.812. (Ndmodld To all who??? it 'nuty concern: 7

' Be it known'that I, IIALPH BAGGALEY, of Pittsburg, Allegheny count-y,-Pennsylvania, haveinvented a new and useful Copper-Smelting Furnace, ofwhich the following is a full, clear, and exact description, referencebeing had to the,accompanying drawings, forming part of thisspecification, which show a copper-smelting plant constructed inaccordance -w ith my invention.

Figure 1 is a vertical section of the turn ace,- and Fig. 2 being asectional elevation of the furnace, the section being on the line II IIof A Fig. 1.

In' the operation of smelting copper sulfid ores a considerable part ofthe expenseis due -to manual labor required in attending and chargingthe furnace. It is important that this work be done regularly andwithsuffiders 6.

'cient frequency and it is the purpose of my invention to providemechanical devices for this purpose which can be operated efficientlyand without manual labor.

In the accompanying drawings, 2 represents the smelting-furnace,havingtwyers 3 3 for the admission of a blast of air.

To charge the furnace with ore, fuel, and

flux, I provide above the smelting zone a latcral charging-h opper 4,havin gverti cal1y-sli d ing doors 5, which open into the-interior of hefurnace and may be operated by air-cylin- The valves of these cylindershave connections 7 extending to the position of the operator on theplatform '8 on the opposite side of the furnace and enable the doors tobe operated individually or together, as desired.

By opening the doors separately in.

the'proper-order the charge can delivered to any portion of the lengthof the furnace, j

and even charging and regular operation of the furnace can thus besecured. The hop per 4 is kept charged from cars 9 with the appropriatemixture of ore and flux, and the extent and frequency of the supply ofore to the interiorof the furnace are governed by manipulation of thedoors 5, as above described.

Within the scope of my invention as defined in the claim the apparatusmay be modified in various Ways without departing from my invention,since I What I claim is A smelting-furnace having a hopper adapted tocontain a body of charge material, an opening extending therefrom intothe side of the furnace, and a plurality of doors cont-rolling theopening, said doors being arranged side'by side in the same verticalplane; sub stautially as described.

In testimony whereof I have hereunto set my hand.
